Anyone try this harness yet and if so how does it work? functionality and reliability.

From the website: Finally, a plug and play "track fan" kit for the 2010+ Camaros that takes the guess work out of overriding the electric fans for additional cooling. This kit includes everything you need - a professionally made, loomed harness, the correct pins already crimped, and a switch that allows you to run the fans on low or high. Works excellent for forced cooling while waiting in the staging lanes!
